title: [Different types of hypoxic preconditioning protect the brain against complete global ischemia].
abstract: Different types of hypoxia, including several new models, protect the brain against complete global ischemia. Hypoxic (stay in hermetic chamber without or with consumption of CO2 and H2O exhaled), circulatory (bleeding), hematic (injections of NaNO2, CoCl2, NiCl2) and tissue (histotoxic) hypoxia (K2-malonate injection) increases cerebral ischemic tolerance in early terms (in hours). Intracerebroventricular injections of NaNO2, CoCl2, NiCl2 and K2-malonate in nontoxic doses have weak effects. These substances act by peripheral mechanisms. Increased ischemic tolerance is accompanied by pronounced hypothermia which closely correlates with a neuroprotective effect. This shows using tolerant strategy.
